L' Geenen HUNTER,"` a citizen of the Province of Syrien: under the protectorate ofthe Republic oi- France, and a" resident of'- the' city of New' York, `loorou'gli' of Man-hrattan;V inl the county and State of- Neiv Yorlqfliave invented a new and use-ful' Improvement' in TvVindovvJGleaning Bevices", of which the'l followingisV a full,

clear, and exa-ot description;

This invention relatesy to' a1 device ffor cleaning Windows; and L has particular refere'rieejtd a device perni'itting the clea-niing` of; Windows entirely from within-the same. V

Ari objecty oit theinvention is` to .provide a? simple and eiiieient means wherebyA the glass surfaces of Windows' may be' readily cleanedfrom' the`V inside" offtheA Windolvvses pe'eiajlly sliding Windows vvfhich ordinarily are' diiicult'to reaclrfron the insicle-lwith# out requiring' the' operator to sita-nd upon' narrow' Window ledges or attempt to reach the outside ofthe Vglass from" Within,v both ofjwlcir conditions rendr'his position" and operationdifloult and dangerous;

Another object is toj provideY means for wash-ing Windows, especially on the' mitside,A by simple manipulation? of a m'echalnic'zall pover which can be manipulated from'with# in althoughoperatedon the WindowA from Without. 1

further obj ect is to provide an apparatus in Which-the" operating" parts ean be readily dismantled and collapsedto' permit th'exn to?w be taken eti' the Windu'iw` and stored avvay,j and also for the purpose of permitting theml to `he' rea'f'lily'readjustedV in different relations to the-window. l i v Ar stillV further object is to pz'lovi'deWin#i dovvfyvasliing'apparatus which can be `very quickly and easily.' accommodated in posi;

tion to Wash the inside as Well as the' outside ofthe Windows.` i i Another goblject' isz tof provide* apparatus Which in its various operations requires milriniIn'A of manipulation and ski-ll on the partotlie operator. w i a' A further object resides 'inL the particular" construction and i arrangement of p'art'scwhiolr are? hereinafter described and ola'imed and The inveirition'is illustratedin the' draw# ings,4 of which-'1v i Figure 1 is a sectional line 'of `Figure 2. y .A

The form of the invention shown in the drawings is a preferred form, althoughI it is understoodlthat modilioations in* the! con:J

struction and arrangement ot' the parts and` in the character of the materials used may be adopted Without departingirom the spirit or the invention.

The invention as illustrated in the drawings includes a base or support l adapted to be mounted and clamped on the" sill of a Window. This base portion l has/on its npper surface a pair of grooves or tracks 2, preferahly-tapered to co-operate with similarly formed tongues 2 on aslidable memloer 3. The member 3 is s lidahle laterally of the baseportion l; By reason' of the taperedtongueand groove engagement of the slidable member 3' with the hase l, the member 3 can' be moved back and forth along the haseportion l but is held rigidly in a horizontal plane.

The slidable member 3 extends trans versely o1 the base 1, and on its lateral edges is provided with turned-over iange portions 4 forming tracks Whicheiitend at right angles to the grooves or `traekvays'in thehase l.v These tracks' are adaptedlto receive a support or platform 5' and permit its'siiding movement on the memberl This platform platform 8 on Whichjis' mounted 1an electri ea'l-fmotor 9 properly Wiredto a source off supply,v andis preferably a high-'speed m`o'- tor.- 'On the' end of shaft 10 of the -m'otor 9 is mounted ai disk orplate 11. Th-islnay bemounted in any suitah-leimfanner 'se' that it can he readily removed atv/ill.r Connected to the edge of the plate or disk 11 ai blish 12, This brush may bec'onn'eoted t0 soV lbrushes'but drying and polishing brushes.

On the rear end of the slidable platform 5 Vis mounted a drum 13. This is -mountedin suitable brackets and operated by a handle 14.: A ratchet 15, of any suitable form, prevents the unwindingof the drum or the' movement ofiit 1n one direction.

A chain or cable or suitable flexible element 16*- is connected to the drum' and passes over a pair ofpulleys 17, one disposed near the bottom ofthe uprights 6 and the other dislsupports G are Vcut outat the bottom, as,

shown at `18, so that the'entire carriage 7 Y and the slidable member from their tracksV Y down or disassembled. v

posed near the tcp of the uprights 6. The other end of this flexible element 16 is connected to the carriage 7. It will beV seen that the weight ofthe carriage and the motor 'and the co-operating parts will keep the cable or flexible element taut and, therefore, the operation of the drum or spindle V13 is such only as to permit the carriage 7 to be elevated; The release of the ratchet mechanism 15 will, by reason of the Weight of the carriage and the motor, permit the carriage and themotor to descend by gravity to the bottom of the frame formed by the uprights 6: The tracks or grooves in the uprights or and everything supported thereon may be removed from the tracks when desired. llhe further dismantling ofthe-device may consist of the removal Vof the disk 11 from the shaft 10 andthe discounting Vof thel motor 9 from theshelf 8. V-This may-be readily-effected by mounting-these elements in arcadily detachable. manner. By removing the carriage'7 and withdrawing-the support 5 the entire device may be easily knocked The ends of the base member 1 are provided with wingsor extensions 19 hinged at theends of the base member in such manner that one or both may be turned, in caseV the base member is disposed within the frame of anarrow window, to'adjust. the length of the base'member to fit the window. In other cases, bothA may be up or'bothmay be down, aszthe conditions require. It is understood, of course,that thedimensions of.

the device can Ybe varied to. suit the general 'Y typ ofwindows with which'it is to'be operate Y Thebase member is preferably on the vice which includes a base member, means on the inside and theoutside. To clean the sill by theV engagement of clamping meinbers 21 with one edge ofthe sill, andthe engagement with the otheredge of thesill of set screws or clamping screws 2O in the well known manner, sothat the base member 1 1 isvery -iirmlypheld in position.

In operating the device, the brush or pad i wils-properly treatediwith the desired cleaning fluid or with soap and-water, and thereafter with clear water, and the motor set in operation. As the motorfoperates, the slidable member 3 is moved back and forth across Vthe sill Vso Vthat the brushismoved across the window to cleanthat portioirof it coming within theV rangefof-pthe brush at that level. Previously the slidable platform or'supp'ort l5 vhas been-set to brin'gthe brush in proper contact withthe vpane of glass onb the outside. After-this particular level of thewindow hasbeen cleaned, the 'frame 13 may-,bel operated to permit the carriage 7 to drop a desiredfamount. VThe slidable member 3Y is then movedtoone side ofthe frame and the motor again started,'where upon the slidable member'is moved -across levels. of the'windouT are thereby cleaned,

`and this cycle of operation may be repeated no the frame to clean-this level. r` Successive for polishingand dryingthe windowyboth;

brush 1Q will bear against theinside of the pane of glass. Y. Y Y .p 1 Itwill, of.. ourse,=be understood that I have described only a preferred forinwhichV the invention may assume, and :which ^inicio cludes the general 'principle'.of operation, whichAv may be' embodied, inv practical, appli- 11.0
